1. Field of the Invention
The present invention relates to a waterproof electrical connector, and more particularly to a waterproof electrical connector adapted for being mounted to an opening defined in a device.
2. Description of Related Arts
U.S. Pat. No. 8,025,530, issued on Sep. 27, 2011, to Abramov discloses a related art. According to the disclosure, a sealed electrical connector comprises a support member, a plurality of electrically conductive elements installed in the support member, an overmold molding with the electrically conductive elements and the support member, a shield mounted on the overmold, and a gasket mounted on the shield. The overmold defines a pair of through holes. The shield comprises a pair of legs inserted through the through holes. U.S. Pub. No. 20120315779, published on Dec. 13, 2012 to Shinya et al., CN Pub. No. 102403618, published on Apr. 4, 2012, to Takeshi et al., and JP Pub. No. 2011-090885, published on May 6, 2011 to Kikuchi disclose related arts.
Therefore, the overmold provides a fluid seal around the electrically conductive elements, but not fluidly seals the legs of the shield and the overmold.
Hence, an improved electrical connector is required to overcome the above-mentioned disadvantages of the related art.
An object of the present invention is to provide an electrical connector that waterproof performance is improved.
To achieve the above-mentioned object, an electrical connector adapted for mounting to an opening defined in a device comprises: an inner insulative member, a plurality of contacts mounted to the inner insulative member, an outer housing mounted to the insulative member, and a shielding member. Each contact comprises a mating end for mating with a mating connector, a mounting end for being mounted to an inner portion of the device, and a connecting portion connecting with the mating end and the mounting end. The mounting ends of the contacts extend beyond the inner insulative member. The outer housing defines a hollow portion, a pair of mounting holes extending through the outer housing, and a pair of injection holes respectively in fluid communication with the mounting holes. The shielding member comprises a body portion and a pair of mounting legs extending from the body portion inserted through respective mounting holes for being mounted to the inner portion of the device. A gap is formed between each of the mounting legs and a corresponding mounting hole. Gules seal the injection holes to prevent fluid flow from the hollow portion into the inner portion of the device.
According to the present invention, the outer housing defines a pair of injection holes in fluid communication with the mounting holes, respectively. Therefore, glue could be injected into the mounting holes to seal the gaps formed between each of the mounting legs of the shielding member and the mounting holes.
Reference will now be made in detail to a preferred embodiment of the present invention.

The outer housing 3 is overmolded with the inner insulative member 1. The outer housing 3 comprises a front face 31 and an opposite rear face 33. The outer housing 3 defines a hollow portion 32 extending through the front face 31 of the outer housing 3. The outer housing 3 comprises a pair of mounting portions 34 located at opposite sides of the rear base portion 35 of the outer housing 3 for being mounted to the device. Each of the mounting portions 34 defines a stepped mounting hole 341 and a fixing hole 342 adjacent to the stepped mounting hole 341. Each of the mounting portions 34 has an inverted-L shape. The outer housing 3 forms a projection portion 314 fully filled with the recess 114 of the base 11 to provide a reinforced connection between the outer housing 3 and the inner insulative member 1. The inner insulative member 1 has a portion extending beyond the rear face 33 of the outer housing 3 to form a shoulder 13 for being accurately fixed by mould in the over molding process. The outer housing 3 defines a pair mounting holes 331 extending through the rear face 33 of the outer housing 3 along a horizontal direction, and a pair of injection holes 351, which is formed in the rear base portion 35, in fluid communication with the mounting holes 331, respectively. The injection holes 351 extend along a direction perpendicular to the horizontal direction. The outer housing 3 comprises a pair of supporting portions 332 projected rearwardly from the rear face 33. Each of the supporting portions 332 is disposed below a corresponding mounting hole 331. The outer housing 3 defines an annular slot (not labeled) in the front portion for receiving a gasket (not shown) for sealing some gaps between the outer housing 3 and the opening of the device. Therefore, the outer housing 3 is tightly molded around and sealingly engaged with the inner insulative member 1 to prevent fluid flow from the hollow portion into the inner portion of the device. The tongue portion 12 is received into the hollow portion 32.
